UNITED STAEEE HARRY QU'ELMS, OF CATSKILL, NEW YORK.

SCREW-CONVEYER DRIVE-CLAMP.

Application filed October 19, 1920.

l/ '0 all whom it may concern Be it known that I, HARRY QUnLMs, a citizen of the United States, residing at Catskill, in the county of Greene and State of New York, ave invented certain new and useful Improvements in Screw Conveyer Drive-Clamps, of which the following is a specification.

This invention relates to clamps and more particularly to a screw conveyer drive clamp.

One of the objects of my invention is the provision of a clamp for supporting a screw conveyer from a drive shaft.

Another object of my invention resides in the construction of a supporting clamp for a screw conveyer and means for joining the respective flights of a conveyer.

A still further object of my invention is directed to an adjustable clamp for connecting the flights of a conveyer and means for supporting the said flights and sections of the drive shaft.

With these objects in view and others which will lee-manifest and suggested as the nature and purpose of my invention are revealed in the following specification and drawing wherein I have shown a practical, yet prefererd embodiment thereof,

Figure 1 shows the invention as applied to a screw conveyer.

Fig. 2 is a perspective view of the clamp.

Fig. 3 is an end view.

Fig. 4c is a top view.

Fig. 5 is a view of the blank before it is bent.

Referring now to the drawing, numeral 1 designates a hollow drive shaft and 2 the conveyer having the usual curved flights 3. Supporting clamps 5. 6 at each end of the conveyer are adapted to support the sectional hollow shaft and its corresponding flights 9, 10 as clearly seen in Fig. 1.

Each clamp comprises a cylindrical, open I, ended body portion 12 having diametrically opposed bolt holes 13 in its top and bottom and corresponding bolt holes 141 in its sides for the reception of gudgeon bolts 14 which are adapted to connect the shaft sections.

Outwardly extending attaching arms 15,

posed edges 17, 18 are connected by a short transverse bolt and nut 19 near their lower portion and cross each other as clearly shown in Fig. 8. Opposed apertures 20, 21 formed in said attaching arms are adapted to receive fastening elements to secure said arms to the ends of the flights of the conveyer sections.

From the above description taken in connection with the drawing, it will now be seen that 1 have devised a novel and improved form of clamp adapted to support a sectional shaft and the flights of a conveyer thereby overcoming the objections of the old form of post and sleeve structures and the frequent breaking of end flights. It is of course to be understood that I do not claim the shaft or the endless flights as this construction is common in conveyers, harvesters, agricultural machinery etc., and it will be readily recognized by those skilled in the art that the clamp may be utilized as a support for the above purpose in various connections, particularly where it is desired to connect the flights of similar conveyors.

In the accompanying drawings, I have illustrated my invention embodied in one form by way of example, and which in practice has been found to be highly satisfactory in obtaining the desired results. It will be obvious however that other embodiments may be adopted, and that various changes in the details of construction may be resorted to by those skilled in the art without departing from the spirit and scope of the invention. It is furthermore understood that the invention is not necessarily limited or restricted to the precise elements shown except in so far as such limitations are specified in the subject matter being claimed.

What I claim is:

1. In a supporting clamp of the class described, a cylindrical body open at both ends for the reception of a sectional driven shaft, a slit formed in said body and obliquely disposed to the longitudinal axis thereof, out wardly extending arms crossing each other and formed integral with said body for con nection with a flight or flights of a screw conveyer or spiral element.

2. In a supporting clamp of the class described, formed of a major parallelogram body adapted to be bent into a tubular sleeve like member, the angularly disposed edges of said body forming a slit obliquely dis posed toward the longitudinal axis of the said body reduced attaching arms extending outwardly from the respective edges and secured to each other near their lower ends, and means for fastening said arms to the flights of a screw conveyer or spiral ele- 10 ment.

In testimony whereof I afiix my signature hereto.
